Answer:

The cost of the bracelet was [tex]\$6[/tex]

Step-by-step explanation:

Let

x------> amount of Carla's savings

y-----> the cost of bracelet

we know that

[tex]y=\frac{2}{5}x[/tex] -----> equation A

[tex]1-\frac{2}{5}=\frac{3}{5}[/tex]

so

[tex]9=\frac{3}{5}x[/tex] ----> solve for x

[tex]x=9*5/3=\$15[/tex]

substitute the value of x in the equation A and solve for y

[tex]y=\frac{2}{5}(15)=\$6[/tex]
